This invention relates to improvements in refrigerating systems, and consists of the novel construction hereinafter disclosed.

An object of the invention is to provide a refrigerating system for a coolerroom, which system includes oppositely disposed units having parallel chambers in which air currents are inducted and educted for cooling the space therebetween, the air currents being contacted with refrigerating sprays in their passage through the refrigerating units.

Additional advantages of the invention will be apparent from the following detailed description taken i1.` connection with the accompanying drawing, in which- VFig. 1 is a plan view of a cooler room showing the system installed therein and taken substantially on the line 1--1 `of Fig. 2.

Fig. 2 is a vertical section of the cooler room and through the refrigerating units.

In the embodiment of the invention illustrated in the drawing, the refrigerating system is shown as installed in a cooling chamber or room 1 constructed in the usual manner with insulated walls. The units are mounted against opposite vertical walls of the cooling chamber 1 and are arranged to direct the cooling currents of air toward the center of the chamber, driving the currents of air across the upper part of the chamber so that the air currents will meet at approximately the center of the chamber and, by gravity, move downwardly in the chamber to cool the contents thereof.

Each of the units comprises a trough 2, preferably located on the floor of the chamber and having a discharge pipe 3 connected thereinto so that the liquid accumulating in the trough 2 may be discharged to a recovery system. A backwall 4 is positioned against an end wall of the chamber 1, said wall having an out-turned portion 5 at its upper end. The wall 4 is preferably connected to and supported by the rear wall of the trough 2. A front wall 6 is supported by and connected to the front wall of the trough 2 and extends upwardly, terminating at a distance below the ceiling of the cooling chamber. An intermediate wall 7 is positioned between the walls 4 and 6 and has an out-turned extension 8 that runs parallel with the portion 5 of the wall 4.

' There are thus formed two parallel chambers 9 F between the walls 5 and 8.

It will be noted that the wall 7 terminates in are a number of baffle walls 11 and, on the wall 'l and extending into the chamber and intermediately spaced, are similar bale walls 12, forming a tortuous passage for the outgoing current of air, the bafe walls serving to drop out moisture from the outwardly moving current of air.

Within the trough 2 is a baille comprising a downwardly inclined longitudinal wall 16 which extends from the rear edge of the trough, and a vertically disposed wall 17. This baille serves to prevent the splash from the sprays entering the lower end of the chamber 10, and thereby provides additional means for freeing the outgoing current of air from moisture.

Across the top of the chamber 9 and positioned below the upper extremity of the wall 6 is a spray header 13 which is equipped with a plurality of spaced nozzles 14 directed downwardly into the chamber 9. The warmer currents of air are withdrawn from the chamber 1 by the siphoning action set up by the plurality of sprays downwardly directed in the chamber 9. It will be understood that the sprays eject a refrigerating liquid such, for example,y as cooled brine delivered to the header from a suitable source of supply under pressure. The incoming air currents coming in contact with the spray are cooled and forced upwardly andl outwardly through the chamber 10 into the cooling chamber. The liquid from the sprays is accumulated in the trough 2, from which it is discharged and returned to the means employed for cooling the brine liquid. The outgoing current of air is freed from moisture by contacting with the battles 11 and 12. The relatively dry cold air from the cooling units is moved across the upper part of l the cooling chamber and circulates downwardly in continuous air currents while the refrigerating units are in operation, thereby uniformly cooling the cooling chamber to the desired temperature. t

In the construction of the unit, it is preferred that the chambers 9 and 10 shall be unobstructed longitudinally and closed only at the ends by walls 15; although, if it is desired, the unit may be made in sections by providing walls intermediate the walls 15.

I am aware that the invention may be modified in numerous particulars without departing from the spirit and scope thereof. I do not limit myself, therefore, to the exact construction shown and described, but what I claim and desire to secure by Letters Patent iszl.
